Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) is recognized globally as a specialized Carbon Steel Bitumen Tanks Manufacturer, delivering high-performance, structurally certified, and thermally advanced containment solutions essential for the global road construction, roofing, and waterproofing industries. Bitumen, a high-viscosity petroleum residue, is critical to infrastructure development worldwide. Its inherent physical property—being solid or semi-solid at ambient temperatures—necessitates that it be stored and maintained at significantly elevated operating temperatures to ensure it remains liquid and pumpable. This demanding thermal service is the paramount engineering challenge, requiring tanks built to withstand high internal temperatures, thermal cycling stresses, and immense insulation loads. Consequently, the storage vessels used, the Carbon Steel Bitumen Tanks, must be meticulously engineered to ensure uncompromising structural integrity, specialized internal heating systems, rigorous defense against corrosion exacerbated by heat, and unwavering adherence to the most stringent international codes, particularly API standards for high-temperature atmospheric storage.
Our expertise is concentrated on fabricating customized Carbon Steel Bitumen Tanks solutions that set the industry benchmark for durability, certified safety, and continuous operational performance across asphalt production plants, road construction depots, and bulk distribution terminals. We focus on delivering solutions that integrate superior structural strength (designed specifically for severe thermal stress), specialized thermal management systems, advanced sludge and water removal features, and strict adherence to major international construction codes, such as API 650. Through meticulous engineering, rigorous quality control, mastery of automated welding techniques, and depth of material science knowledge, our Welded Steel Tanks are essential assets of maximum reliability, thermal efficiency, and long term service life, securing the critical bulk storage segment of this vital infrastructure material globally.
Storing bitumen requires managing extreme heat, which places unique, magnified demands on the tank’s material science and structural design. As a specialized Carbon Steel Bitumen Tanks Manufacturer, Center Enamel focuses on integrated design solutions for this high-temperature service.
Elevated Operating Temperatures: Bitumen must be maintained at a high temperature to keep its viscosity low enough for pumping and mixing. This continuous application of heat requires sophisticated, reliable heating systems (often thermal fluid coils or electric heaters) integrated within the tank structure.
Thermal Stress and Structural Integrity: The carbon steel tank shell, floor, and roof structure must be robustly specified to handle the severe, continuous thermal stresses induced by the elevated operating temperature and the thermal cycling that occurs during loading and unloading. Compliance with API Standard 650 for atmospheric storage is mandatory, with specific design factors applied to manage these thermal effects.
Insulation System Load: The tanks require thick, high-performance external insulation and cladding to minimize energy loss. The tank structure must safely and structurally accommodate the weight and mounting stresses of this heavy insulation system.
Sludge and Purity Mitigation: Over time, heavy contaminants and some components of the bitumen settle, forming a dense, potentially corrosive sludge at the tank bottom. The design must incorporate systems for continuous removal of this material to prevent floor corrosion and maintain operational capacity.
Aluminum Dome Roofs: A robust, fixed roof is essential to maintain thermal efficiency and protect the insulation layer. Aluminum Dome Roofs are utilized because they offer a superior, lightweight, and corrosion-resistant external structure that is ideally suited to support the necessary heavy insulation jacketing and prevent rainwater damage or heat loss.
Our expertise ensures that every Welded Steel Tank is engineered for both the heavy-duty containment and the specialized, high-temperature thermal environment required for bitumen storage.
The manufacturing process utilized by Center Enamel for Carbon Steel Bitumen Tanks is a highly specialized operation, adapting the structure to safely integrate and manage extreme heat.
The structural foundation must be robustly specified for continuous high-temperature operation, well beyond typical oil storage conditions.
API 650 Adherence for Heat: Large capacity vertical tanks are fabricated in strict accordance with API Standard 650, with specialized design calculations applied to the shell and component thicknesses to safely manage the stresses induced by the elevated operating temperatures. This includes careful consideration of material selection within the carbon steel range to ensure strength retention at the specified temperature.
Automated Welding and NDT Verification: Utilizing certified, high-grade carbon steel plates, our advanced automated welding systems ensure continuous, full-penetration, defect-free seams. Every critical weld on the Welded Steel Tanks is verified using Non Destructive Testing NDT—such as radiographic examination and ultrasonic testing—to confirm monolithic structural integrity, which is exceptionally critical for high-temperature vessels under load.
Nozzle and Manway Reinforcement: The tank structure is fabricated with reinforced nozzle connections and manways designed to accommodate high-temperature piping, specialized thermal fluid connections, and the heavy loads of associated insulation and cladding systems.
Effective, safe temperature control is the most critical function of a bitumen tank, requiring seamless integration of specialized hardware.
Internal Heating Coil Integration: We specialize in the structural welding and support of highly efficient internal thermal fluid (hot oil) heating coil systems or specialized electric heating panels. The coil supports and penetrations are meticulously welded into the carbon steel shell and floor, designed to manage temperature gradients and ensure the bitumen remains at its required pumping viscosity while minimizing localized thermal stress points.
Insulation and Cladding Provisions: The tank structure is fabricated with robust, pre-engineered attachment points for high-efficiency external thermal insulation and heavy-duty weather jacketing (metal cladding). This comprehensive system is essential for minimizing energy consumption and maintaining the stable, high storage temperature required for flowability.
Sloped Bottom and Sludge Mitigation: Tank floors are fabricated with a pronounced sloped bottom leading to a dedicated sump or draw off point. This crucial feature ensures that heavy sludge, sediment, and any residual water contamination are efficiently channeled for removal, which is vital for preventing under-deposit corrosion and preserving the tank's floor integrity.
Maintaining the high internal temperature and protecting the insulation system are key functions of the roof structure.
Aluminum Dome Roofs: For large diameter Carbon Steel Bitumen Tanks, we integrate Aluminum Dome Roofs as the primary external cover. These self-supporting geodesic structures are lightweight, highly corrosion resistant, and ideally suited to support the immense weight and loading of the thick thermal insulation and cladding necessary to prevent heat loss. Aluminum Dome Roofs provide a superior, low-maintenance external barrier, preventing rainwater accumulation and protecting the critical insulation layer from the elements, ensuring maximum thermal efficiency.
Venting and Safety: Due to the elevated storage temperatures and potential for pressure fluctuation, tank venting systems must be precisely designed to manage thermal expansion and contraction and adhere to API 2000 for venting products stored at elevated temperatures.
The high storage temperature and potential for water contamination significantly accelerate internal corrosion in Carbon Steel Bitumen Tanks.
The primary defense is material selection suitable for the service temperature and generous material thickness.
Increased Corrosion Allowance: A standard corrosion allowance—an extra thickness of steel—is typically increased for bitumen tanks, proactively extending the tank's service life against inevitable internal corrosion accelerated by heat and any water/sulfur compounds present in the residue.
High-Temperature Coatings: While internal linings are often impractical due to the extreme heat, specialized high-temperature coatings may be applied to internal components not exposed to the bulk liquid, or tested coatings used in the vapor space above the liquid level.
The heavy insulation system requires robust external defense.
External Coating Systems: The tank exterior receives specialized, heat-resistant coating systems (on areas not covered by insulation) and robust protection underneath the insulation to prevent atmospheric and environmental corrosion of the carbon steel shell.
Aluminum Dome Roofs: The inherent corrosion resistance of the Aluminum Dome Roofs provides superior, long-term defense against external elements, particularly vital in coastal or high-humidity environments where the roof is subject to continuous weather exposure.
